BOTTLE-WASHING MACHINE.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed January 27, 1906- Serial No. 298,103.

To all whom it may concern:

Be it known that I, GEORGE W. Gonmvs, a citizen of the United States,residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented a certain new and useful Improvement inBottle- I/Vashin Machines, of which the following is a speci cation.

My invention relates to a new and useful improvement in bottle washingmachines, and has for its object to so construct such a machine as toprovide a stationary recess or mandrel for insertion within the neck ofa bottle and by which the bottle may be supported while the brush isrevolved therein.

With these and other ends in view, this invention consists in thedetails of construction and combination of elements hereinafter setforth and then specifically designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, I will describeits construction in detail, referring to the accompanying drawingforming a part of this specification, in which Figure 1 is an elevationof a machine made in accordance with my improvement showing the brushsecured therein. Fig. 2, a central section of the machine illustratingthe manner of securing the brush in the spindle. Fig. 3, a detail viewof a portion of the spindle, mandrel and the clamp for holding themandrel in place.

Referring to these. drawings A represents the frame of the machine whichconsists of a foot B, adapted to be secured to a bench or other suitableobject by means of the screw C, but one of which is here shown, and withthis frame is cast the bearings D having j ournaled therein the spindleE.

F represents the drive pulley which is secured upon the spindle by meansof the set screw G, and this pulley when set upon the spindle serves tohold the latter in place, as will be readily understood.

H are suitable oil cups secured in each of the bearings for lubricatingthe same.

I represents a bracket cast or secured to the frame and terminating in asocket J, upon which is fitted a clamp K, held in place by the bolts L,and this arrangement is for clamping the mandrel M to the bracket inalinement with the spindle. This mandrel is hollow so as to permit thepassage of the stem N of the brush 0 therethrough, the inner end of saidstem passing into a suitable hole P formed in the spindle in order thatit may be there secured by the set screw From this description it willbe seen that when the brush is in place it will revolve with thespindle, while the mandrel will remain stationary, and when it isdesired to wash a bottle the latter is forced over the brush 0, thebristles of which will be deflected until passing into the body of thebottle, when they will spring outward to their normal position, the neckof the bottle passing on to the mandrel which will then serve as a restrelieving the brush and its stem from any strain during the washingoperation.

Heretofore considerable time has been lostin the washing of bottles bymachines, and many bottles broken at the mouth on account of thevibrations of the stem of the brush, but by my improvement thesedifficulties are entirely overcome and any sidewise strain comes uponthe brush or the shank thereof, and the shank is compelled to run trueat all times as it is housed and guided within the mandrel.

The clamp K permits of the ready removal of the mandrel for adjustmentor the substitution of another when one becomes worn.

Having thus fully described my invention what I claim as new and usefulis,

A bottle washing machine consisting of a frame formed with a horizontalbase, a foot depending therefrom at an intermediate point and disposedat right angles thereto, a pair of spaced parallel uprights integralwith said base, said uprights each terminating in integral enlargedbearings which project beyond the sides of said uprights, a curved armformed integral with said base and with the inner of said uprights atthe juncture of the latter with said base, said arm terminating in anenlarged seat alining with said first named bearings and spaced fromsaid bearing of the inner upright, a mandrel in said seat, a platelikeclamp engaging said mandrel, bolts secured to said clamp for securingsaid mandrel, a spindle in said bearings having an I affixed mysignature in the presence of two opening in one enfi, a bgush hgluipg ashank subscribing Witnesses. extendin throug sai man e and into said oper ling and a set screw extending GEORGE GOEHNS' 5 through the spindle toengage the brush WVitnesses:
